A particle is moving on a straight line in such a way that its velocity v is given by v ( t ) = 2 t + 1 for 0 ≤ t ≤ 5 where t is

measured in seconds and v in meters per second. What is the total distance traveled (in meters) by the particle between times t = 0 seconds and t = 5 seconds ? (Do not enter the units)

Answer:

The total distance traveled by the particle is S = 30.

Step-by-step explanation:

Given that velocity,

v(t) = 2t + 1

To find the total distance travel, we integrate the velocity function, v(t), to obtain the distance function s(t), and evaluate the resulting distance at the interval given. That is at t = 0 to t = 5.

Integrating v(t) with respect to t, we have

s(t) = t² + t + C.

At t = 5

s(5) = 5² + 5 + C

= 25 + 5 + C

= 30 + C

At t = 0

S(0) = 0 + 0 + C

= C

The required distance is now

S(5) - S(0)

= 30 + C - C

= 30.

Answer:

30

Step-by-step explanation:

Given the velocity of a particle to be;

V(t) = 2t+1

To get the distance travelled by the particle, we will use the formula

Velocity/speed= Distance/time

V = dS/dt

dS = Vdt... 1

Substituting the value of the velocity function into equation 1, we have;

dS = (2t+1)dt

Integrating both sides to get the distance S, we have;

∫dS = ∫(2t+1)dt

S = 2t²/2+t + C

S(t) = t²+t+C

To get the total distance travelled between the times t=0 and t=5, we will plug the value of t = 0 and t=5 into the function of the distance and then subtract as shown;

S(0) = 0²+0

S(0) = 0

Also

S(5) = 5²+5

S(5) = 25+5

S(5) = 30

Distance travelled between both times will be S(5) - S(0)

= 30-0

= 30

What are the coordinates of the image of C if it is reflected across the x-axis?
Svetradugi [14.3K]

Answer:

(-2, 4)

Step-by-step explanation:

~When reflecting a point of the x-axis, the x value (or first number inside the parenthesis) does not change.

The reason the x-value does not change is because you are reflecting over the x-axis, making the point go up or down. That will change the y-value but the x-value only changes if you move to the left or the right. In this case, you can see that the point's x-value is -2, so that will not change. It's current y-value however is -4. When reflecting over an axis, the number that is changing (in this case the y-value) will just be flipped from positive to negative, or vise versa. In this case, -4 will be reflected to be 4, making point C reflected over the x-axis (-2, 4).

Emilio bought 5.65 of green grapes and 3.07 pounds of red grapes
NISA [10]

The weight of each bag is 0.545 lb .

<h3>What is weight ?</h3>

Weight in maths is the value of the mass of an object on a measuring scale , It is measured in pound , ounce , kilogram etc.

It is given that

Total weight of green grapes = 5.65 lb

Total weight of red grapes = 3.07lb

Total weight = 5.65 +3.07 = 8.72   lb

Total number of bags = 16

the weight of each bag

= 8.72 / 16

= 0.545 lb

Therefore the weight of each bag is 0.545 lb .

The complete question is

Emilio bought 5.65lb  of green grapes and  3.07lb of red grapes. He divided the grapes equally into 16 bags. If each bag of grapes has the same weight, how much does each bag weigh?
